.I nasogoe g known that I, ANDREW jat'Nau htonyin the-county of Burleigh ant State 0 North Dakota, have invented jce'i tain'newand useful Improvements in Automatio ThrottlesOperators, of which the following is a specification.

' invention relates to traction engines and more particularly to throttle operating attachments-therefor, and has for its object .to provide a throttle operator for use connection with traction engines when attached to plows or other farm implements likely to ,meet obstructionsdnthen' paths which Would tend to either break the implements themselves, or disconnect them from the en- .gine, the arrangement of-the presentv attachment bein such that it is operated to close the thrott ebefore'injury to the implement Other objects-and advantages will be apparent from the following description and it will be understood that changes in the speoific-structure shown and described may be made within the scope of the claims without de arting from the spirit of the invention.

of the chain with the throttle-lever.

Referring, now. to the drawings, there is shown a traction engine 5 with its plow rig ging 6, which is connected to the engine by means of anextensible spring The throttle lever of the engine is ndicated at 8 and enga ed with this lever, there is a collar 9 inclu ing jaws 10 which are connected at one side of the lever by means of a thumbbolt 11, so that the collar adjustable upon the lever.

The chain 14 is supported upon suitable last named An eye 12 is carried by the collar and has engaged therein, one end j Patented Feb; 25,1905.

It will thus be seen that engagement of an obstruction by one of the plows 16 or by therigging 6 itself which would impede the progress thereof would cause an extension of the spring? with movement of the chain to stop t e engine 5/ Should the arresting of the rigging 6 take place ona down grade, under such conditions that the' en 'ine 5 coul be readily sto ed, it, will be seen that the spring'13 we'uiii expand and finally prevent bending of the lever- 8.

In this case, the chain 14 extends forwardly and around a pulley A, and thence to the riggin 6. I v
